The Schedule referred toV in these Letters Patent :m making part of the same.

To all whom 'it may concern: i

. Be it known that `LLEVI F. SMITH, of Philadel` phia, in theV countyof Philadelphia and'in the StateV of Pennsylvania, `have invented certain new and use` inl Improvements in Steanrcyliuder,Lubricator; and

`do hereby declarethat the following is a full, clear, vand exact description thereof', reference Ybeing had to the accompanying drawing and to the letters ot' referc iice marked thereon, making a part of this specific-a-v tion. y p The nature ot' my invention consists in Vthe' construction andai-rangement of a fgraduating-lubricator, for steamfcylhnlers', or other places where a lu- Y fbricator Vis necessary, and `in which oil, tallow, or suct maybe used at pleasure, the l flow of the lubricating materialbeing graduatedlso as to supply any desired number of drops per minute.` l In order to enable othersjskilled'in the art to 'which my invention appcrt-ains to make'and use the same, I will nowproceed to describe its construction and open' ation, reterriug'to the annexed drawing, in'which ,Figure l is a longitudinai'vertical section of my entire lubricator; f "Figure 2is a vertical section of the top oil-gauge, attached to my lubricator; and "`.,Figur`e 3 `is a side view of the cup that forms a t'unnel,for pouring in oil or melted tallow.

represents the bowl or globe, which contains the lubricating.'substance, having a single opening in its `top',aroiind which is formed cup, B, acting as a g funnel, for pouring in oil or melted tallow. f

`Fromthe cup B two arms, C (l, extend upward a suitable distance, and between the upper ends of saidarms is pivoted a rock-shaft, D, the object of wlnch will be presently described.

-In the bottom of the `bowl A is screwed the hase E, whichvextends downward suitable distance, and

l `is provided with screw-threads on its outer side, to

l be screwed into the cylinder, or other place where the lubricator is to be used. v

At or on the upper end of the base E is formed Y the strainer G', to prevent any foreign substance, cony tained in the lubricating material, from passing down to the valve,` especially when suet is used where there are always more or less substances which are not consumed.v

From the inside ot the strainer, passages, a a, lead downward, conductingthe lubricating material to the `valve b, whichfits snugly in` its seat, d, formed within the base E. l, The valve b is formed upon or attached to the end of a stem, ,whiehpasscs up through a hollow screw, H, andis' held by a nut at its upper end. y

The screw H is screwed through the center ot' the baseE, and upon it is formed, at a suitable point, la disk, I, which forms the cap for the strainer By turningthe screw H in one direction the valve Z1 will be raised andv opened, and when turned in the other direction it will be lowered and4 closed. The means for turninglthe screw will be hereafter set forth.

l The valve-b being loose-that is, can turn around at the lower end of the screw H-it will last much longer than if it was fixed, and, when necessary, it can readily be ground in. Y 1 Through the rock-shaft D is passed a stem, J, provided with a collar or enlargement, i, which bears against they under side of the shaft, preventing the stem from moving up through the shaft.

vOn the upper end of the stem J are screw-threads, for screwing intora socket, K, the lower endof which bears against the upper side of the rock-shaft. The socket K, after 'being screwed in place on the stem J, is fasteuedby a pin passing'through. 0n the socket K is formed a disk, L, having on its upper side, near the circumference, lugs, h h, which project upward, and tit in notches, made for that purpose, in the under side of the wooden handled. This handle is, also, on its underside, provided with a circular recess, in whichthe disk L tits.

From the center ofthe disk L a screw passes up'- ward through a hole in the center of the handle M, anden said screw,'on the upper side of the handle, is placed a nut, N, surrounded by a cap or flange, O, having a downward-projecting rim, m, around its periphery.' This cap and rim iitin corresponding `recess and groove in the upper side of the hand-le M, as shown in iig. 1, whereby the said handle is held firmly, and prevented from splitting, which is very often the case with such wooden handles.

The lower end of the stem J is screwed into a hollow sleeve, P, upon which is formed a valve, a, `to tit in theopening to the bowl A, and ,the lower end ot' said-sleeve extends down into the bowl, and provided with a wrencl1,R, which Afits upon the upper end of the hollow screw H. The upper end of this screw H has square corners, but is longer one way than the other, so that, when the sleeve P is lowered to fit the wrench',

it can only be put on in one way.

By turning the handle M in one direction, the sleeve I will be raised so as to open the valve n, whcn'oii or tallow may be poured into the bowl. The oil. or tallow passes down 'on one side of the sleeve, and the air escapes on the other, thereby obviating the necessity of a separate air-hole. As soon as the howl is illed, the sleeve is lowered so as to close the valve. l

When it is desired to use suet, the sleeve is raised entirely up, so as to clear the wrench R, when it may be turned to one side by the rock-shaft D turning upon ils pivots, leaving the entire opening to the bowl free. When filled, the sleeve is turned back and lowered again.

On the sleeve is secured a level', S, by means of which the saine may bc turned with the stem J, to raise or lower the valve b, to allow more or less of the lubricating material to pass out.

From the lever S a-finger, p, points to the side or edge ofthe cup C, which is graduated so that the said'finger will show how many drops per minute the valve l) allows to escape.

From the top and bottom of the bowl A, apipe, T, leads horizontally outward, each to a valve-chamber or box, V, which two chambers are connected bya vertical glass tube, W, by means of which the amount or height of the lubricating material in the bowl can be seen at all times.

lach of the valve-chambers V, is provided with a valve, s, upon the cud of a stem, t, which passes through-thc outer side of the chamber, and provided .with a wheel or handle, X, for turning.

Upon a collar on the outer side of the valve-chamber is screwed a nut, lz, through which the stem t is also screwed.

The valvesI is formed, as shown iu iig. 2, conicalon both sides, and suitable valve-seats are formed in the box, both where the pipe T enters, and where the stem tpasses through.

\Vhcn it is desired to have the valve s open, the

stem is screwed out, so that the valve will t in the' seat iu the outer end of the chamber, thus obviatiug the necessity of a stufiing-box or packing, to' keep this joint tight.

If the glass tube lV should break, or, from any other cause, it is desired to close the valves, the stem is at once screwed in, so that the valve tits in the seat at the entrance of the pipe T. The only time when the joint of the stein t and nut Iv can possibly leak is while the valve s crosses from one side of the chamber to the other.

This arrangement may be used with great advantage ou water-gauges, or for other purposes.

Having thus fully described my invention,

What I clainr as new, and desire to secure by Letters Patent, is-

ards C C, and base E, with strainer G, passages a a, and valve-seat d, all construct-ed and arranged substantially as and for the purposes herein set forth.

2. The arrangements of the hollow screw H, with cap I', stem e, and valve b, all substantially as shown and described` 3. The hollow sleeve P, provided with valve m, wrench It, and lever S, and used in combination with the stein J and rock-shaft D, substantially as and for the purposes herein set forth.

. 4. The combination of the disk L, lugs h h, handle ranged substantially as and for thc purposes herein set forth.

5. In combination with the hollow sleeve P and lever S, the finger p and graduated edge of the cup B, substantially as and for the purposes herein set forth.

6. The combination of the valve-chamber or box Y, with two valve-seats opposite each other, as described, double valve s, steml t, and nut c, all constructed and arranged to operate substantially as and for the purposes herein set forth. f

7. The combination of the bowl A, base E, tubes T T, valve-chambers V V, with their seats and double valves, and the gauge XV, all constructed and arranged substantially as and for the purposes herein set forth.

hereunto set my hand this 4th day of June, 1870.
